Product Overview – P-TZ-18/21 Cylindrical Cell Insulation Paper Applicator
PPCELL’s automatic cylindrical battery insulation paper sticking machine is purpose-built for high-volume application of insulating paper (highland barley paper/kraft paper) to the positive terminal of cylindrical lithium-ion cells. Serving the lithium battery industry, this equipment processes 18650, 21700, and 21650 cylindrical cells for EV battery packs, power tools, e-bikes, and consumer electronics. The machine is used in the battery pack assembly process – specifically the insulation application stage after cell sorting and before module assembly. Production scales range from mid-volume production lines to high-throughput battery pack assembly facilities, with easy changeover between cell formats.
The system features a stamping cutting mechanism that applies insulation paper to four cells simultaneously per cycle, achieving a production rate of 60-70 PPM (4,000 cells per hour) – significantly reducing manual labor and ensuring consistent insulation placement.

Frequently Asked Questions
Q1: What cell formats does this insulation paper sticking machine support?
A: The machine supports 18650, 21700, and 21650 cylindrical cells. Additional formats such as 26650, 32650, and 32700 are available upon request with custom tooling. Tooling changeover typically takes approximately 30 minutes.
Q2: What types of insulation materials can this machine process?
A: The machine supports a wide range of materials including highland barley paper, kraft paper, rice paper, RET protective tape, and PVC. Material roll specifications are flexible, accommodating various widths and core diameters.
Q3: How does the fault alarm system work?
A: The system features audible and visual fault alarms that trigger when issues such as material shortages, jams, or component malfunctions occur. The alarm enables rapid diagnostics, minimizing downtime and simplifying troubleshooting.
Q4: What is the tail material clearing function?
A: The machine includes a one‑click tail material clearing function that automatically removes residual material at the end of each roll. This feature simplifies roll changes, reduces waste, and minimizes operator intervention.
Q5: Can this machine be integrated into an existing battery pack assembly line?
A: Yes. The machine is designed for seamless integration into existing production lines with belt conveyor transmission. It can be configured for manual or automatic feeding depending on your line layout and throughput requirements.
Q6: What is the expected die life for the stamping cutting mechanism?
A: The high-speed steel cutting dies offer excellent wear resistance, significantly extending service life compared to standard steel dies. Die life varies based on material type and throughput but typically exceeds hundreds of thousands of cycles before requiring replacement or re‑sharpening.
Q7: What is the difference between this machine and manual insulation application?
A: Manual insulation application is labor‑intensive, inconsistent, and prone to positioning errors. Our automatic machine delivers consistent ±0.1mm placement accuracy, 60-70 PPM throughput, and eliminates operator fatigue – significantly improving quality consistency and reducing labor costs.
